@TRex22 @BenjiWiebe I'll probably merge and release this weekend, but I wanted to see if you had any thoughts before I do.

[TRex22]

Cool Ill look over now

[TRex22]

👍 Yeah looks good to me...

The reason I used log and not puts was around the fact that it does not behave exactly like puts does. i.e. puts prints given text and then a new line. Here it's kind of printing above the progress bar. More of a philosophical reason

[paul]

@TRex22 The reason I chose puts is because of the symmetry with other IO-like object in Ruby. I don't know if we will, but it might be nice if you could supply an instance of ProgressBar in place of other things like $stdout that expect to be able to puts, and it wouldn't be too hard to add print and write, should the need arise.

Is this going to get rolled up into a release?

[paul]

@ppkn I think I was waiting for feedback in the other PRs, then forgot all about it. I'll cut a new release today!

@ppkn done, released 1.3.2: https://rubygems.org/gems/progress_bar
